This is a thin 1/8" thick foam core mount. It is extremely lightweight and very easy to trim. It is suitable for mounting small and large prints. Slightly more fragile than Foam Core 3/16" thick, it is suitable in applications where a print must be inserted in a frame or moulding with limited clearance.
Styrene sheets are an excellent alternative to traditional cardboard mounts. Cardboard mounts are made of natural paper fibers. These fibers are hydroscopic. They can absorb and give off moisture in response to environmental humidity. They actually behave like sponges. This change in moisture content causes cardboard to expand and contract. When this change occurs after a print has been mounted on one side of a cardboard mount it can result in a bow or warp in the board. This effect becomes more pronounced as the size of the board is increased.
This is a 40 point (approximately 1/16" thick) cardboard mount. It is suitable for mounting smaller prints. Because it is a fiber based board it is affected by changes in moisture content and may warp or bow in larger sizes or in situations where there may be large changes in humidity. This board is not available in sizes larger than 20x24".
